Scientific Validity

All NewMetrica instruments are developed using well established psychometric methodology, recognised as the gold standard for design of instruments to measure human pain and  health-related quality of life.

That process includes testing for validity and reliability as well as responsiveness where instruments are used to measure clinical change over time.  Changing the  presentation of the instrument by translating it into another language,  requires further linguistic and cultural validation and this has been carried out for the acute pain tools in a variety of languages.

Psychometric instrument design is an iterative process in which instruments are refined and re-tested with new populations in new contexts and for new purposes. This is the focus of our ongoing research

An established, peer-reviewed publication record highlighting scientific validity, reliability and responsiveness for all NewMetrica instruments can be accessed here.

"I have been using VetMetrica for over 18 months now and have found it has revolutionised how I monitor patients and collect data. It is very easy to set up and the tools are intuitive and easy to follow

VetMetrica provides a great window into the animals’ quality of life and how it feels in its home environment. This has enabled me to better care for these patients and also collect good quality data for future publications. I cannot recommend VetMetrica enough. "

Andy Armitage, Greenside Vet Practice

Vetmetrica offers a valuable tool in assessing the impact of chronic pain on quality of life in dogs & cats. When treating chronic pain, most owners say that quality of life is paramount and they want their pet to be pain free. Vetmetrica engages owners and gives them the ability to measure quality of life.

"I found that a computer based scale run by Newmetrica... the same great people who gave us the Glasgow Pain Scales... is a wonderful way to get reliable quality of life scores.  You can find it here at http://www.newmetrica.com/vetmetrica-hrql/.  It generates a non-biased decision using a computer algorithum.  Answers are weighted differently so it is harder for the caregiver to subconsciously manipulate the outcome.  And they cannot go back and change their answers like they can on paper form"  Dr Mike Petty

“Firstly I want to congratulate you and your team on the important work you are doing in the field of pain assessment and in particular the NewMetrica HRQL tool which I think is a real game changer!” – Leon Warne.

“It goes without saying that within our dealings with the team at NewMetrica we found them to be consistently helpful and professional throughout”.
